High Tibial Osteotomy.

During a high tibial osteotomy, surgeons remove a wedge of bone from the outside of the knee, which causes the leg to bend slightly inward.

Another operation called high tibial osteotomy can sometimes be done to reconstruct an arthritic knee and delay the need for a total knee replacement by a decade or so.

The most common type of osteotomy performed on arthritic knees is a high tibial osteotomy, which addresses cartilage damage on the inside (medial) portion of the knee.
